<p class="wp-embed-aspect-16-9 wp-has-aspect-ratio">We can accomplish this task by one of the following options:</p>
<ul type="video" class="wp-embed-aspect-16-9 wp-has-aspect-ratio">

</ul>
<hr class="wp-block-separator has-alpha-channel-opacity"/>
<h2>Method 1: Use startswith() and endswith()</h2>
<p class="has-global-color-8-background-color has-background">This method uses <a rel="noreferrer noopener" href="https://blog.finxter.com/python-string-startswith/" target="_blank"><code>startswith()</code></a> and <a rel="noreferrer noopener" href="https://blog.finxter.com/python-string-endswith/" target="_blank"><code>endswith()</code></a> in conjunction with <a rel="noreferrer noopener" href="https://blog.finxter.com/introduction-to-slicing-in-python/" data-type="URL" data-id="https://blog.finxter.com/introduction-to-slicing-in-python/" target="_blank"><code>slicing</code></a> to remove one set of double quotes from a string.</p>

print(web_name)</pre>
<p>The first line in the above code snippet declares a string containing two (2) sets of double quotes and saves this to the variable <code>web_name</code>.</p>
<p>The following line calls the <code><a rel="noreferrer noopener" href="https://blog.finxter.com/if-then-else-in-one-line-python/" data-type="URL" data-id="https://blog.finxter.com/if-then-else-in-one-line-python/" target="_blank">if</a></code> statement with the <a rel="noreferrer noopener" href="https://blog.finxter.com/python-string-startswith/" target="_blank"><code>startswith()</code></a> and <a rel="noreferrer noopener" href="https://blog.finxter.com/python-string-endswith/" target="_blank"><code>endswith()</code></a> functions. Both functions are passed the argument (<code>'"'</code>). </p>
<p>This statement checks to see if <code>web_name </code>starts with and ends with the above argument.

<h2>Method 2: Use Regex</h2>
<p class="has-global-color-8-background-color has-background">You can use the <a rel="noreferrer noopener" href="https://blog.finxter.com/python-regex/" data-type="URL" data-id="https://blog.finxter.com/python-regex/" target="_blank"><code>regex</code></a> method <code><a href="https://blog.finxter.com/python-regex-sub/" data-type="post" data-id="5861" target="_blank" rel="noreferrer noopener">re.sub()</a></code> to remove one set of double quotes from a string.</p>

<p>The first line in the above code snippet imports the <a rel="noreferrer noopener" href="https://docs.python.org/3/library/re.html" data-type="URL" data-id="https://docs.python.org/3/library/re.html" target="_blank"><code>re</code></a> library. This allows access to and manipulation of strings to extract the desired result.</p>
<p>The following line declares a string containing two (2) sets of double quotes and saves this to the variable <code>msg</code>.</p>
<p>The next line uses <a rel="noreferrer noopener" href="https://blog.finxter.com/python-regex-sub/" data-type="URL" data-id="https://blog.finxter.com/python-regex-sub/" target="_blank"><code>re.sub()</code></a> to search this string for any occurrences of double quotes, removes the same and saves the result back to <code>msg</code>.

<p>The first line in the above code snippet declares a string containing two (2) sets of double quotes and saves this to the variable <code>mission</code>.</p>
<p>The following appends the <code>replace()</code> function to <code>mission</code> and is passed two (2) arguments: </p>
<ul>
<li>the string to replace, and </li>
<li>the string to replace it with. </li>

<h2>Method 5: Use Pandas</h2>

<h2>Method 1: Use startswith() and endswith()</h2>
<p class="has-global-color-8-background-color has-background">This method uses <a rel="noreferrer noopener" href="https://blog.finxter.com/python-string-startswith/" target="_blank"><code>startswith()</code></a> and <a rel="noreferrer noopener" href="https://blog.finxter.com/python-string-endswith/" target="_blank"><code>endswith()</code></a> in conjunction with <a rel="noreferrer noopener" href="https://blog.finxter.com/introduction-to-slicing-in-python/" data-type="URL" data-id="https://blog.finxter.com/introduction-to-slicing-in-python/" target="_blank"><code>slicing</code></a> to remove one set of double quotes from a string.</p>

print(web_name)</pre>
<p>The first line in the above code snippet declares a string containing two (2) sets of double quotes and saves this to the variable <code>web_name</code>.</p>
<p>The following line calls the <code><a rel="noreferrer noopener" href="https://blog.finxter.com/if-then-else-in-one-line-python/" data-type="URL" data-id="https://blog.finxter.com/if-then-else-in-one-line-python/" target="_blank">if</a></code> statement with the <a rel="noreferrer noopener" href="https://blog.finxter.com/python-string-startswith/" target="_blank"><code>startswith()</code></a> and <a rel="noreferrer noopener" href="https://blog.finxter.com/python-string-endswith/" target="_blank"><code>endswith()</code></a> functions. Both functions are passed the argument (<code>'"'</code>). </p>
<p>This statement checks to see if <code>web_name </code>starts with and ends with the above argument.

<h2>Method 2: Use Regex</h2>

This allows access to and manipulation of strings to extract the desired result.</p>
<p>The following line declares a string containing two (2) sets of double quotes and saves this to the variable <code>msg</code>.</p>
